The opposition INDIA bloc will hold a "maha rally" at Delhi's Ramlila Maidan on March 31 to "safeguard the country's interests and democracy", AAP leader Gopal Rai said on Sunday.

The announcement comes after Delhi Chief Minister Arvind Kejriwal (55) was arrested by the Enforcement Directorate (ED) on Thursday from his official residence in connection with an excise policy-linked money-laundering case. A court on Friday sent the AAP national convenor to the central agency's custody till March 28.
